hope this helps :) also if u can pls mark me as brainliest it would be a great help
Answer:
The assumption is quite reasonable.........
A lightbulb contains Ar gas at a temperature of 295K and at a pressure of 75kPa. The light bulb is switched on, and after 30 minutes its temperature is 418 K. What is a numerical setup for calculating the pressure of the gas inside the light bulb at 418K?
Explanation:
P

Had the light bulb been sealed at normal pressure during its manufacture, what do you think might occur when it is operated?
s, p, d
Explanation:
the number of sublevels for an energy level is as follows:
for n = 1 : s
for n = 2 : s, p.
for n = 3 : s, p, d.
for n = 4 or higher : s, p, d, f.
